Is there any way or configuration that I could do to use My Page Flip with high resolution images?
You can use high resoulation image files for best quality in your publication. (But this method is bring performance on some computers)
You can make vertical, horizontal or square flipping books. You don't have to use dimensions in online demos. Edit width and height by width="400" height="600" (it must becomes same pages dimensions) and edit others items (for colors) in Default.html file. You can use larger pages in the My Page Flip but it's better not to use many and too large sized pages. We advise you to separate into a few parts. For high quality readability, you can use vectoral texts in SWF formatted pages if you haven't many pages else if you don't use it in too pages.
